Leak to dry to treated, one company in Eltham

Eltham's housing runs from Edwardian and Victorian terraces around Well Hall to bay-fronted 1930s semis in Eltham Park and post-war council stock in Middle Park and Coldharbour. Rear-addition flat roofs, converted lofts, and original Edwardian plumbing sit alongside newer extensions, giving the area a wide mix of ageing waterproofing details prone to hidden leaks.

Common leaks in Eltham homes

Flat roof extensions over kitchens and bathrooms

Many of Eltham's 1930s semis and Victorian terraces have had single-storey rear extensions added, most topped with felt or asphalt flat roofs. These coverings perish with age, and once the membrane splits or the upstand flashing pulls away from the brickwork, rainwater tracks along the joists and appears as staining on the ceiling below, often well away from the actual entry point.

Bathrooms leaking into rooms below in converted terraces

Streets around Well Hall and Westmount Road have Edwardian and Victorian terraces where bathrooms were retrofitted above kitchens or reception rooms. Shower trays flex, silicone seals around baths perish, and grout on tiled floors cracks, letting water seep through the subfloor. Because these houses have suspended timber floors, water can travel some distance before it shows as a stain on the ceiling underneath.

Perished pipework in older solid-wall properties

The Victorian and Edwardian housing stock nearer central Eltham still contains original lead or galvanised steel pipe runs hidden beneath floorboards and behind skirting. Joints corrode and fittings weaken over decades, so a slow escape of water can soak into timber floors and party walls unnoticed for weeks, encouraging rot and mould before any damp patch becomes visible in a living space.

What our customers say

★★★★★

I recently used a damp and mould specialist company and was extremely impressed with the service from start to finish. From the initial survey, they were knowledgeable, thorough, and took the time to clearly explain the cause of the issue rather than just treating the symptoms.

Tip: If your water meter ticks over with every tap off, or a wall or ceiling stays damp with no obvious cause, there is a hidden leak. Finding it early is far cheaper than repairing the mould and damage it leaves behind.
